On July 14, 2015, the United States and its international negotiating partners reached an agreement with Iran on its nuclear program: the Joint Comprehensive Plan of Action (JCPOA) or the Iran nuclear deal. The agreement, which was formally adopted on October 18 of the same year, would only go into effect after Iran completed a number of initial steps.
On January 16th, 2016 (known as “Implementation Day”) the deal was implemented after the International Atomic Energy Agency (IAEA) reported that Iran had made the necessary reductions to its nuclear program and granted the IAEA the access necessary to verify the agreement. In exchange, the United States and other world powers agreed to waive nuclear-related sanctions.
Before Implementation Day, the IAEA certified that Iran:
- Eliminated 98% of its uranium stockpile.
- Removed and destroyed the core from its Arak reactor, blocking the production of weapons-grade plutonium.
- Ripped out over 13,000 centrifuges (two-thirds of total). Those removed in the process must be placed under continuous IAEA monitoring.
- Halted all uranium enrichment activities at the underground Fordow site.
- Allowed the IAEA to implement the safeguards necessary to monitor Iran’s nuclear program and implemented transparency measures, such as the Additional Protocol, to permit greater access to inspectors.
- Gave the IAEA the information it needed to assess the possible military dimensions of Iran’s nuclear past.
Going forward, Iran must:
- Possess no more than 300 kg of uranium enriched up to 3.67%
- Operate no more than 6,104 centrifuges
- Cease uranium enrichment at the Fordow facility
- Ship out all spent fuel from reactors
- Allow the IAEA continuous monitoring and inspections its key nuclear facilities
- Abide by limits on centrifuges research and development
The P5+1’s role
In return, the United States, the European Union, and the United Nations lifted some sanctions related to Iran’s nuclear program. The sanctions infrastructure has remained in place in case Iran violates the agreement and the re-imposition of sanctions is required.
In addition, the United States will still maintain key sanctions, including a prohibition that prevents Iran from using the U.S. commercial markets and banking system. The United States will also maintain sanctions targeting Iran’s support for terrorism, its human rights abuses, and its missile program.
